What's the date 21 months from today?

Solution

Sunday January 17, 2027

Date Range: 21 months

21 months from today is 17 Jan 2027, a Sunday. Adding 21 months in the future is usually just counting from April; however, longer calculations will push us from 2025 into 2026. Even if the calculation remains within the year, I usually take note of the 13 days left in the middle of April, to prep for left over days or weeks in the calculation.

How we calculated 21 months from today

All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how adding 21 months to today's date gets calculated on each visit:

Started with date inputs: starting point: 17 Apr, Units to add: 21 months, and year: 2025
Noted your current time of year: 13 days in middle of April
Added 21 months from current day: 17 Apr, factoring in there are 13 days left in before May
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2025 fiscal calendar.

Ways to calculate 21 months from today

Just calculate it: Start with a time from today calculator. 21 months is easiest solved on a calculator. For ours, we've already factored in the days in + all number of days in each month and the number of days in 2025. Simply add your months and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
Use April's calendar: Begin by identifying on a calendar, note that it’s Sunday, and the total days in May (trust me, you’ll need this for smaller calculations) and days until next year (double trust me, you'll need this for larger calculations). From there, count forward 21 times by months, adding months from 17 Apr.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+21 into the cell. If you want to add weeks, multiply your day by 7 and months/years will take their own calculation due to the changing days of the week. To find 21 months workdays, convert to days but use =WORKDAY(TODAY(), [number of days], [holidays]) into the cell. [number of days] is how many working days you want to add, and [holidays] is an optional range of cells that contain dates of holidays to exclude.

21 working months from today

21 months is Sunday January 17, 2027 or could be Friday October 15, 2027 if you only want workdays. This calculation takes 21 months and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday January 17, 2027 date.
